I again.

Be it known that I, KARL J UNG, manager, a subject of the German Emperor, and-residingat 58/59 Gross-Beeren strasse,-Berlin,-in the Kingdom of Prussia, German Empire, have invented certain new and use-- ful Improvements in Shaping-Machines, of which the following is a specification.

This invention relates to a slide-moving device for machine tools, more particularly for tool slides of shaping machines. In these machines, it is usual-to move the tool slide by means of a rocking lever which is driven by meansof a link. The pin of the slide block is mounted on the driving gear wheel. The result of this construction is that, more particularly whenthick shavings areremoved during the working stroke, there takes place a canting of the rocking lever and a severe stress both on the pin of the slide block and on the bearing journal for the toothed wheel. The depth of cut is therefore limited by the construction of the; slide or carriage movement, even when the tool is suitable for removing thick shavings.

This'invention obviates the said disad vantage by supporting the gear wheeluin direct proximity to the pin for the slide block, by setting ofi? for instance the toothed wheel on the outside and supporting it As the stress is chiefly produced during the working stroke it is in most cases suflicient to arrange an abutment only on one side of the toothed wheel. vIn that way, it is possible to adjust to a very deep cut and the output of the machine is considerably increased; V n

The drawings illustrate three construe tional forms of this inventionin. its application to a shaping machine, Figure being a side elevation of the shaping-machine,'partly in section, and Fig. 2 a partial cross-section through "Fig. 1. Fig. 3 shows a modified constructional form of the support according to the invention. Fig. 4 is a side view of the right-hand part of Fig. 3. Fig. 5 is a further modification;

As shown in the drawing the shaping machine itself is of the well known construction; The slide a for the tool is driven by rocking lever b which is pivoted on one side to the tool slide and on the other side by means of a rod 0 to the machine frame. The rocking lever is provided with a slot excessive stress"onithepin e, the link and of the rocking lever, as wellf Patented oct. 20, 1914.

in wliich theisl'ide-block (Z moves;

e mounted infthe slide block is arranged onthefgear wheel 7" driven in the known manner. i y I In order to avoid, during hcavyicuts, an

as anexcessive stress on thebearing journal n of the toothed wheel f,the gear wheel 1s according to this invention supported in direct proximity to the rotating plane of the pin 6. In the drawing, this support is gear wheel 7 on effected by providing the its, outer side with an offset, so that the toothed rim j has on its outside a smooth ring g. With the said ring 9 engages a roller 72 mounted in a rockinglever la rotatable about a" point i on the machine frame, and can be adjusted by means of a setscrew m and held in contact with the ring 9. The-roller k is arranged in such a manner thatduring the working stroke, it takes up the pressure exercised byfthe pin a on the gear wheel "7 and thus does away with the above-mentioned, disadvantages T j" As a rule, it is suificient, fortaking up the pressure, to use the'construction shown in the Figs. .1 and 2 of thedrawings. In 85 certain cases it may be' necessary forthe purpose "of'taking up the stresses "durlng the return stroke, to arrange an abutment also on the other side as shown in Figs 3" and 4.- Ihisfurther abutinent may be formed as a roller omounted 1n. arocking' a canting of lever 19'- fastened on a' bolt 9.; 'This bolt bears an arm '1' lying against a set screws toothed .wheel: may. be supported comby which the roller can be adjusted and held ,inzcontact, with the ring 9. Also the v pletely around the ringfl, so that the wheel is supported during the whole forward and return strokes. Such support t is shown in Fig. '5 of the'drawings. Y

Having now particularly described and ascertained the nature of mysaid invention and in what manner the same is to be'per; 1 formed, I declare that what I claim is f' 1. In a slide-moving device for machine I tools more particularly for shapin'g ma chines in combination a driving spindle, a

rotating machine element mounted on the end ofvthe driving spindle, a pin carried by said machine element and transmitting I the movement to the slide and an additional I support for the said machine element pro-.

vided in the plane of rotation of the pin and on that face of the said element which tends to resist the cutting stress.

2. In a slide-moving device for machine tools more particularly for shaping machines in combination a driving spindle, a

of the said gear wheel, which tends to resist the cutting stress. s

3. In a slide-moving device for machine tools-more particularly for shaping machines in combination a driving spindle, a rotating .machine element mounted on the end of the driving spindle, a pin carried by said machine element and transmitting the movement to the slide and an additional support for the said machine element provided in the plane of rotation of the pin and on that face of the said element which tends to resist the cutting stress and operative only at intervals.

4. In a slide-moving device for machine tools more particularly for shaping 1na-;

chines in combination a driving spindle, a rotatlng machine element mounted on the end of the driving spindle, a pin carried by said machine element and transmitting the movement to the slide and an additional support for the said machine element provided in the plane of rotation of the pin and on that face of the said element which tends to resistthe cutting stress and operative only during the working stroke.

In a slide-moving device for the machine tools more particularly for shaping machines in combination a driving-spindle, a rotating gear wheel mounted on the end of the driving spindle,"a pin carried by said gear wheel and transmitting the movement to the slide and an additional support for the said gear wheel arranged in direct proximity "to the pin, said gear wheel being provided with an annular projection en gaging with the said additional support.

6'. In a slide-moving device for machine tools more particularly for shaping machines in combination a driving spindle, a rotating gear wheel mounted on the end of the driving spindle, a pin carried by said gear Wheel and transmitting the movement to the-slide and an additional support for the said gear wheel arranged in direct proximity to the pin, said gear wheel being provided with an annular projection and said additional support consisting of rollers engaging with said annular projection.

7. In a slide-moving device for machine tools more particularly for shaping machines in combination a driving spindle, a rotating gear Wheel mounted on the end of the driving spindle, a pin earned by said gear wheel and transmitting the movement to the slide and an additional support for the said gear wheel arranged in direct proximity to the p111, sald gear wheel being provided with an annular projection and said additional support consisting of rollers engaging with said annular projection in such a manner that they take up the pressure of the pin during the period of the highest pressure.

8. In a slide-moving device for machine tools more particularly for shaping machines in combination a driving spindle, a rotating gear wheel mounted on the end of the driving spindle, a pin carried by said gear Wheel and transmitting the movement to the slide and an additional support for the said gear Wheel arranged in direct proxilnity to the pin, said gear wheel being provided with an annular projection and said additional support consisting of rollers engaging with said annular projection and being adjustably arranged. y .In testimony whereof I have affixed my signature in presence of two witnesses.
